RE: Trunnion on an Elbow

practice is there but not accepted universally, some companies allow, some will not..... fact is that it works and simplify supporting.......... i have never come across any failure..... for critical lines (hot lines), as long as anylysis is perfect and welding is correct...... there seems to be no problem....... for cold lines there is at all no problem....

         the only exception which i can think off. is if the line is cut in future for maintenance and same elbows have to be used and support location changes......here again, i say, use the same elbow and prepare the support at other location.....

         in fact, i am also into this controversial discussion......... but to avoid problems..... at the moment not using supports at the elbow......

         may be others are able to put more light on this issue.........

Dear members,

Whether welding a trunnion on an elbow & using it as a support is accepted practice universally ? Infact, I have used it numerous times in many projects.

But I am met with a stiff resistance for one of our on-going projects. Result is, supporting becomes tedious.

Request all put in their views & any bad experiences of resulting failures ...

Thanks,
Shreedhar.
